Everything is dark. There’s no one around. The raindrops fall heavily. Suddenly, the call ― it’s time to dig. The man digs with his bare hands until he is covered in mud. But he keeps going. His goal is to find the enigmatic creature making that unique call ― a sound that has never been heard before. At first sight, this scene could be part of a horror or a mystery movie. But it has nothing to do with the zombie apocalypse. This is how German herpetologist (an expert on amphibians and reptiles) Raffael Ernst described his experience trying to identify frogs in the Amazon. And the effort paid off. Ernst was part of the discovery of a new species, which has been dubbed the “Zombie Frog.” Its orange-spotted appearance is indeed quite peculiar, but the 40-millimeter (1.5 inches) amphibian is not an undead monster.
